#Parnet Connections?
7 messages in this thread
Anyone happen to have the pin connections for making up a parnet cable?
I've looked in the libraries but haven't seen anything obvious, just lots of
software.
I have the software setup from when I visited someone a while back, who had a
cable and connected up to my machine, but I had no need of it myself back then.
Now I need to copy from an A3000 to an A1200. Can anyone help?

The parnet DL I have has the pinouts in it.

This might help (from the parnet docs):
MAKING A CABLE
The following connections need to be made on a DB25 cable:
You are making a cable that connects the two PARALLEL ports of your Amiga
together.
CABLE: Connect D7-D0,SEL,POUT, and BUSY across,
Connect ACK (FLAG interrupt) to SEL locally:
(2-9) D7-D0 ———— D7-D0
(12) POUT ———— POUT
(11) BUSY ———— BUSY PARALLEL PORT
(13) SEL –+——+– SEL
(10) ACK -/ \- ACK
(18-22) GND ———— GND (18-22)
Double check the gender for the DB25 connectors you will need to connect to
your Parallel Port.
A500/A2000, Parallel port is Female so you need a Male connector A1000,Parallel
port is Male so you need a Female connector.
The easiest thing to do is to buy a premade cable with all 25 lines passed and
DB25 connectors on both ends (Double check the gender's that they match before
you buy the cable!) And then rip it apart and cut-and-seal those wires which
are not supposed to be connected. You also need to bridge ACK to SEL as per
the diagram above ON BOTH ENDS OF THE CABLE, as shown above.
** NEVER PLUG IN AN UNMODIFIED CABLE BETWEEN THE TWO COMPUTERS!
** DOUBLE CHECK YOUR CABLE BEFORE INSTALLATION!
WARNING! INTERFERENCE WITH SERIAL-PORT.
The RI (Ring Indicate) line on the Amiga's serial port
uses the SEL line to source a transitor. This interferes
with the SEL line which, as you can see, is part of the
network.
Be sure that
(a) either no serial cable is attached or that
(b) It doesn't connect RI or that
(c) your modem doesn't connect RI internally.

Karl,
Many thanks for the pinout info – this was just what I was looking for 😎

You can thank a large hard drive and Steve Ahlstrom, who made it easy to import
documents into Autopilot. <G> And you're welcome.

Karl,
With respect to the RI line interfering with the SEL line…
Maybe that explains the following:
I have an external modem on serial port and a Migraph scanner in the parallel
port. When the telephone rings (voice call, fax or data), the scanner light
blinks in rhythm! This has always made me very nervous. But everything seems
to work. I wonder what would happen, though, if I was scanning a document when
the phone suddenly would ring. And I've never tried scanning while on line with
the modem.
Could be. This is the first I've heard of it myself, but your experience
certainly sounds suggestive.
